Colitis
About this trial
This is an interventional treatment trial for Colitis
Eligibility Criteria
Inclusion Criteria Untreated mCTCAE grade 2-4 diarrhoea or colitis, or persistent mCTCAE grade 2 diarrhoea after administration of loperamide or equivalent for mCTCAE grade ≤ 2 diarrhoea No signs of colonic perforation or infection Age ≥ 18 Understands the nature and purpose of the study and the study procedures and has signed informed consent Is able to read, understand, and complete questionnaires and daily components of the patient Diary for the study period Histologically confirmed malignant solid tumours Treatment with immune checkpoint inhibitors (anti-CTLA-4, anti-PD-1 or anti-PD-L1) within the past 12 weeks. Immune checkpoint inhibitors can be administered as single agents or as combination therapy with anti-CTLA-4 and anti-PD-1 No probability of a concomitant treatment (e.g. laxatives) other than the immune checkpoint inhibitor being the causal drug for the colitis or diarrhoea Prior treatment with immune checkpoint inhibitors is allowed Usage of prednisolone ≤ 10 mg daily for non irAE is allowed Diagnostic work up including screening for viral hepatic infection and QuantiFERON-TB for mycobacterium tuberculosis must be requisitioned but will not need to be reported prior to study enrolment Women of child bearing potential must have a negative serum (preferred) or urine pregnancy test within 72 hours prior to registration. Note: women of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e. females who have had evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons. Patients of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator, during the study treatment period and after the study treatment: for at least 6 months after the last study treatment, or depending on the duration antineoplastic treatment Note: A highly effective method of birth control is defined as a method which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include: Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal) Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable) Intrauterine device (IUD) Intrauterine hormone-releasing system (IUS) Bilateral tubal occlusion Vasectomized partner Sexual abstinence Exclusion Criteria Prior history of inflammatory bowel disease, colitis, or diarrhoea requiring treatment with any corticosteroid, or any other immunosuppressant medication Prior history of recurrent bowel disease including symptomatic diverticulosis Current positive testing for Clostridium difficile or other colonic infection Current bacterial infection requiring antibiotic treatment, or systemic fungal infection Ongoing antibiotic treatment for any reason Treatment with systemic corticosteroids within the last four weeks prior to study enrolment (daily usage of prednisolone ≤ 10 mg for non irAE conditions is accepted) Concurrent immune-related adverse events requiring immunosuppressant medication of any kind Known hypersensitivity or contraindications to systemic corticosteroids or infliximab Prior history of viral hepatitis with a positive viral load, known untreated mycobacterium tuberculosis, or known active herpes zoster infection

Standard of care - Methylprednisolone
Treatment with infliximab
Subjects are hospitalised Day 1 and for at least 4 days. It is accepted that participating centres handle the subjects on an outpatient basis as long as all study requirements are met. Methylprednisolone 80 mg intravenously (body weight 40-80 kg; methylprednisolone 1 mg/kg if body weight < 40 or > 80 kg) will be administered from Day 1 until mCTCAE ir-colitis/diarrhoea grade ≤ 2 and hereafter converted to oral prednisolone. During tapering, if ir-colitis/diarrhoea increases from grade 2 to ≥ grade 3, or from grade < 2 to ≥ grade 2, re-assessment including diagnostic workup will be performed, and the patient will be evaluated for rescue infliximab.
Infliximab will be administered Day 1 or latest Day 2 (within 48 hours). Infliximab infusion is handled as standard by skilled staff. A second dose of infliximab will be administered if ir-colitis/diarrhoea has not resolved to grade ≤ 2 on Day 7. Methylprednisolone 80 mg (body weight 40-80 kg; methylprednisolone 1 mg/kg if body weight < 40 or > 80 kg) intravenously is co-administered from Day 1 until mCTCAE ir-colitis/diarrhoea grade ≤ 2 and hereafter converted to oral prednisolone. Initial dosage of infliximab is 5 mg/kg. Dosage of infliximab for subjects referred to a second dose of infliximab will be left to the discretion of the treating physician. In the event of failure of infliximab, second line biological immunosuppressant treatment will also be left to the discretion of the treating physician.
